Shuffler is a security automation and orchestration platform (SOAR) designed to simplify and accelerate security incident response. It provides a visual, drag-and-drop interface for building automated workflows, known as “Shuffles,” that can perform a wide range of tasks. What makes Shuffler particularly ingenious is its ability to integrate with numerous security tools and data sources, allowing for seamless data correlation and automated decision-making.

Imagine, for example, a scenario where a suspicious email is detected. With Shuffler, you can create a Shuffle that automatically retrieves the email headers, analyzes attachments with a sandbox, checks sender reputation against threat intelligence feeds, and isolates the affected user’s device – all without manual intervention. This level of automation frees up security analysts to focus on more strategic tasks and complex investigations.

Shuffler’s key features include:

Visual Workflow Builder: A user-friendly drag-and-drop interface for creating and managing Shuffles.
Integration with Security Tools: Supports a wide range of security tools and data sources, including SIEMs, firewalls, threat intelligence platforms, and endpoint detection and response (EDR) solutions.
Automated Incident Response: Enables automated investigation, containment, and remediation of security incidents.
Data Correlation and Enrichment: Correlates data from multiple sources to provide a comprehensive view of security events.
Customizable Workflows: Allows for the creation of custom Shuffles tailored to specific security needs.
Community-Driven Development: Benefits from the active contributions and support of a vibrant open-source community.

Installing Shuffler can be done via Docker, making it platform-independent and relatively easy to set up. Here’s a step-by-step guide to installing Shuffler using Docker:

Install Docker and Docker Compose: Ensure that Docker and Docker Compose are installed on your system. You can download them from the official Docker website: https://www.docker.com/products/docker-desktop.
For Linux systems, you can typically install them using your distribution’s package manager. For example, on Debian/Ubuntu:
```
sudo apt update
sudo apt install docker-ce docker-compose-plugin
```
Clone the Shuffler Repository: Clone the Shuffler GitHub repository to your local machine:
```
git clone https://github.com/Shuffle-Team/Shuffle.git
cd Shuffle
```
Configure the Environment: Shuffler uses environment variables to configure its settings. Copy the `env.sample` file to `.env` and modify it as needed. Pay close attention to the database settings (e.g., `DATABASE_URL`, `DATABASE_USER`, `DATABASE_PASSWORD`).
```
cp env.sample .env
nano .env
```
Adjust settings like the admin username and password. It’s *crucial* to set a strong password for the admin user.
Start Shuffler with Docker Compose: Run the following command to build and start the Shuffler containers:
```
docker compose up -d
```
Access Shuffler: Once the containers are running, you can access Shuffler in your web browser at `http://localhost:8000` (or the appropriate address based on your Docker configuration and `.env` settings).

Important Notes:

The first time you access Shuffler, you’ll be prompted to create an administrator account.
Shuffler requires a PostgreSQL database. The Docker Compose configuration sets up a PostgreSQL container for you, but you can also connect to an existing PostgreSQL instance by modifying the `.env` file.

Usage: Building and Running Your First Shuffle

Once Shuffler is installed, you can start creating your own Shuffles to automate security tasks. Here’s a simple example of a Shuffle that retrieves the IP address information using the VirusTotal API:

Log in to Shuffler: Access Shuffler in your web browser and log in with your administrator credentials.
Create a New Shuffle: Click on the “New Shuffle” button to create a new workflow.
Add an Input Node: Drag an “Input” node from the left-hand menu to the canvas. Configure the Input node to accept an IP address as input. Name it “IP Address”.
Add a VirusTotal Node: Search for the “VirusTotal” app in the app store (you may need to add the app first). Drag a “VirusTotal IP Lookup” node onto the canvas.
Connect the Nodes: Connect the output of the “Input” node to the “IP Address” input of the “VirusTotal IP Lookup” node.
Configure the VirusTotal Node: You’ll need to provide your VirusTotal API key. This is a sensitive credential, so store it securely.
Add an Output Node: Drag an “Output” node onto the canvas. Connect the output of the “VirusTotal IP Lookup” node to the “Output” node. Configure the Output node to display the VirusTotal analysis results.
Save the Shuffle: Click the “Save” button to save your Shuffle. Give it a descriptive name, such as “VirusTotal IP Lookup.”
Run the Shuffle: Click the “Run” button to execute the Shuffle. Enter an IP address in the “IP Address” input field and click “Execute.”
View the Results: The output of the Shuffle will be displayed in the Output node, showing the VirusTotal analysis results for the specified IP address.

This is a basic example, but it illustrates the core principles of building Shuffles. You can create more complex workflows by adding more nodes, connecting them in different ways, and configuring them to perform various security tasks.

Here’s an example of a more complex Shuffle for phishing email analysis:

Input: Email (raw format).
Actions:
- Parse email headers (From, To, Subject, etc.).
- Extract URLs from email body.
- Check URLs against threat intelligence feeds (e.g., VirusTotal, AbuseIPDB).
- Check sender’s email domain reputation.
- Send email content and headers to a sandbox for analysis.
- Based on results, tag the email as suspicious or clean.
Output: Analysis report with risk score.

This Shuffle automates the initial analysis of phishing emails, allowing security analysts to quickly identify and respond to potential threats.
